Opinion on Matthew Bond vs. Wireworld vs. Silversmith Fidelium Speaker Cables

Dear Forum, I'm interested about your collective opinion on Matthew Bond versus Wireworld Platinum/Gold Eclipse versus Silversmith Fidelium speaker cables.  Please note that I'll be connecting the cables between my Bryston 7B ST monoblocks and my Dali Euphonia MS-4 speakers.  Preferentially these will be coupled in a bi-wire configuration at the speaker.
